Description

NullPointerException occurs in org.apache.ignite.internal.MarshallerContextImpl#registerClassName on trying to compare mappedName.className() of already existed typeId mapping with the new one clsName has come as a parameter.

Actually org.apache.ignite.internal.processors.marshaller.MappedName#className may not be null but it was. So we should check clsName comes in MappedName constructor, to prevent same NPEs in the future.
